Presentation!
Read and analyze the problem.
How do you feel when you
have some fun with friends?
Is it good to be friendly?
Why?
1. Who watched the football
game?
2. What surprised them about
the sports ground?
3. How many people came to
watch the game?
4. Do you know how big is
that?
Answer the questions
below:
11. Let us visualize the number of people came
to watch the game!
Can you imagine how big is 10 542?
Using blocks, flats, longs, and units or ones,
we are going to visualize 10 542.
12. Let us do the first activity!
Using blocks, flats, longs, and units or ones, we are going to visualize 10 542.
1 block = 1 000, 1 flats = 100, 1 long = 10 and unit = ones
Ready let us visualize 10 524 by writing below the number of blocks, flats, longs and units
10 blocks 5 flats 4 longs 2 units

Let’s Explore and Discover!
A group of farmers donated a
total of 12 364 kilograms of rice to
the typhoon victims.
Can you imagine how big the
number 12 364 is ?
One way you can imagine is to
think of discs to represent the
number.
Can you visualize the number
using number discs.
